To all whom it may concern lZe it known that 1, Farmers Senor, a citizenof the United States, and resident of l hiladelphia, county ofPhiladelphia, and State of Pennsylvania, have invented an lmprovement inEmbossing Printing; Presses, of which the following is a specitieation.

The object of my invention is to provide a suitable means, in anembossing printing press, ,for removing: the surplus ink from the wipingweb and returning it to the ink well; and further to provide means fortreating the ink laden wiping web to a sol vent whereby the surplus inkis more easily removed therefrom and collected as above stated and alsoleaving thepaper web in condition whereby it may be used as a byproductfor stock in paper making.

h'ly object further, is to provide a protected source of solvent supplyfrom which the solvent may be automatically fed to the solvent applyingmeans (movable with the wiping web frame), so that only a small quantityof volatile solvent is exposed at any moment, but whereby applying meansis replenished in a more or less continuous manner, to the end that thepress may be operated for long periods without danger of fire whichwould result from too large a quantity of solvent in exposed conditionin the operative portions of the machine.

lVith these and other objects, hereinafter set out, in view, myinvention consists of certain constructions and combinations of partsfully described in the following spccifications and more particularlydefined in the claims.

.My invention will be better understood by reference to the accompanyingdrawings, in which :-Figure l is a sectional elevation of anembossingprinting press embodying my improvements; Fin. 2 is a camdetail for operating the wiper; Fig. 3 is a cross sectional view ofmeans for applying a solvent to the paper wiping web; Fig. 4 is a planview of the same; Fig. 5 is an elevation of a po tion of the solventfeeding means: and Fig. 6 is a sectional view of the immediate means forremoving the surplus ink from the web.

The general construction of embossing printing presses having automaticwiping devices is well known in the art, and while Specification ofLetters Patent.

I do not in this application make claim to the machine broadly,nevertheless for imparting a better understanding of my improvementstherein, 1 have shown in Fig. l a general view of the operative partsand their relation to each other, and'will now briefly describe thesame. 2 is the main framing, 3 is the stamping plunger, and 4 is the diecarriage and die secured therein. The die carriage is reciprocatedhorizontally, from the position shown, backward under the wiper pad 15and to a position to receive ink by the ink applying roller 9, andthence forward again to the impression position shown. When the die ismoved backward to receive ink, the wiper frame and pad 15 are *aised sothat the paper wiping web 14 does not touch the die; but when the diehas been inkedand moved forward, the wiper pad 15 is moved downward intowiping position for pressing the paper web l-l into contact with the dieas it passes beneath for causing the surplus ink upon its surface to bewiped off upon the web to leave the die clean except for the ink in theengraved grooves, as in intaglio printing. The carriage and die 4; arere" ci 'Jrocated by the rocking lever 5 and links 6, 6, jointed togetherat 7, one of the links being hinged to the carriage and the other to thelever 5. The hinge 7 has guide rollers which traverse the guideway 8, sothat the links fold at the termination of theoscillation of the lever 5to give a'dwell to the carriage and die during the printing or embossingoperation. The inking roller is carried by levers 10 which are rocked bysuitable means operated from the main shaft In fact, all of the poweremanates from this main shaft, but it will not be necessary to describein detail the several instrumentalities employed, as these may be of anysuitable construction so far as the utility of my invention isconcerned. The means for raising and lowering the wiping pad is shown inFigs. 1 and 2, and comprises a rocking lever 29 having at one end a linkconstruction 30 which carries the wiping frame and pad 15, said leverhaving at its other end connection with a power applying rod 32 guidedat its upper end by the shaft and hinged at its lower end to theaforesaid lever. The rod 32 has a roller 33 working in a cam groove 31of a cam secured to the said main shaft 34:, This means recip- 14; bythe knife 25, it "falls upo I ing a trough frame ha rocates the Wipingframe and pad at properly timed intervals, as will be understood.

The wiping web is of paper and wound in a roll 16, supported so as to beunwound therefrom as required. A friction strap 16 weighted at 16applies a braking action to prevent spinning under the intermittentpull. The web 1% passes from the roll 16 over guide 17 and betweenrollers 18 and 18 thence over a guide rod 19 on the wiper frame, thenceunder the per pad 15 thence upward and over the solvent applying roller20, thence under the drag roller 21. thence over the scrapim knife 25,and thence under the guide 26 to the winding mandrel 27. The mandrel 27is intermittently driven to properly feed the web through the machine insuch manner that it is fed when the embossing is taking place and whenthe wiper pad is out of action.

Referring to Fig. 6, it will be seen that the web 14 is bent over thescraping knife 25 at such an angle to insure the surplus ink upon itsunder side being; "fully scraped oil, but without abrasion of the paper.This is accomplished by having the lower portions of the roller 21 andthe guide 26 be low the scraping edge of: the

nite 25; or more particularly, it is essential that the scraper edge beabove the plane across the bottom portions of the guide parts 21 and 26.it is also important that the roller 21 shall put a drag upon the web sothat a substantially uniiorm friction shall be put narrow webs than wideweb chute 28 and. is ten d (Fig. 1). The ink in th by the feed rollerand t 11 to the inking rol r 9, r'iiicl. the die as before 0Consid-erimg now meansQthe roller 20 is loosel C its bearings i6 in opentop he? s i 44 secured to and moving; with frame. Immediately below asolvent carrying means ado solvent to the roller s pocket in whichstrips of wick; o6 are placed and which are kept in Contact with thebottom of the roller 20. one side of the wick pocket is solventreceiving: well 3? having small. ports 38 leadingfrom its bottom to thelower portion of ti e wick pocket (Figs. 3 and l), and outside oi"- thewell 3'? is an overflow chamber 39 which may receive any accidentaloverflow of solvent to remove it out of possible contact with the wicks36. This trough frame 35 is adjust able vertically 45:5 on the frame erand the quired may be had by adjusting screws ll". By this means anydesired pressure between the wicks and the roller 20 may he had. Thesolvent may be supplied to the well 37 by a pipe 40 leading downwardfrom the reservoir 21. The extent of feed may be adjusted by thesight-teed e2 havingthe usual adjusting nozzle; and the solvent may becompletely shut off, when d sired by a valve 43 in the pipe 40. It ispreferable that the valve e8 be suilieiently low in pipe .4) that thspace therein between said valve and the sight-teed device will justfill the well 37 and saturate the webs, so that after the machine hasbeen shut down, the valve 4:3 may be turned on full when starting upagain without oit overflowing oi the device. While it do not restrictmyself to any paricular character of solvent, gasolene. turpentine orother free solvent for the ink may he employed.

I will now describe the means for feedingthe wiping; web. its letorestated, this is accomplished by imparting rotary motion to mandrel. 27upon which the paper wipinn; web is wound and after it has been tingmeans may be similar to those heretofore employed in a March 8. 1910, inwhich the mandrel, correoing to mandrel 27 in this application,.itermittently rotated by power transmi connections of which sprocketchain 68 part. So far as my present invention is the mandrel 2'? may beundernod as an intermittently driven paper web winding mandrel. of anysuitable construction which is at for the purpose of pullino upon theweb to maintain it taut and wind it into a roll with a speedcornmensurate he feeding of the web by the mandrel is filled web, themay be re- 1 toe oneration repeated. In mathis c ass t--- said powertransconnectiens are of such nature that nt is imparted to the so that eweb is also given an intermittent ion but as such devices are well knowntorn a nart of the present invenion, no details description of them willnecessary The wind action of the mandrel causes given le qvh of cleanweb to be drawn un- 1' the wiping "cad 15, and at the same time musesthe inlr carrying; web 14 to pass over the solvent applying roller 20and the scrap extent of its vertical adjustment re- .tchine otthischaracter, for example as shown in Letters Patent No. 951 481 dated thewinding; m .ndrel of he construcing knife 25. lhis having been done, andthe carriage and die 4 having been moved under the wiping pad (butwithout touching the web) to a position to receive ink from the roller 9when moved forward, the wiping pad 15 is moved downwardly by the actionof cam 31 (Fig. 2), and the carriage and die l moving forward cause thedie to wipe its inkd surfaceupon the under surfa .e of the web 1 belowthe said wiping pad 15.

By my improvements the paper web containing; the ink wiped from the dieis sub jected to a solvent by the roller 20 and associated means in sucha manner that the ink is l rought to an excellent condition by which itis easily removed by the scraper 25 over which the paper is drawn sothat the valuable ink may be collected without removing the fiber of thepaper. in this manner, a material quantity of the ink is returned foruse and a minimum quantity is left upon the web, the latter beingsuiiiciently meager as not to objectionably irnpair the paper stockwound upon. the mandrel 27, and consequently not only is there economyin ink, but the lay-product of the waste paper is a material factor ofsaving.

l/Vhile l have described my improvements in the form which I haveemployed common cially and found well suited to the requirements of theinvention, nevertheless I do not confine or restrict myself to thedetails, as these are susceptible of modifications and changes withinthe scope of mechanical skill without departing from the spirit of theinvention.

Having; now described my invention, what I claim as new and desire tosecure by Letters Patent, is

1. in means for applying solvent and the removal of ink from awiping webof an emaossing printing press, employing a vertically reciprocatingframe having a wiping pad under which the web passes, a stationaryscraper for removing the surplus ink from the wiping web, combined witha solvent applying device movable with the frame and its pad and adaptedto apply a solvent to the inked web before it reaches the scraper, saidsolvent applying device and scraper being greatly separated to allow asufiicient interval of time for the ink to be softened before removal bythe scraper.

2. Means in the embossing printing press for removing ink from thewiping webthereof, consisting of a roller over which the inked web isdrawn, a reservoir for solvent, a wick extending upward from the solventreservoir and in contact with the roller for applying solvent thereto ina restricted but uniform manner, and a scraper arranged at the deliveryside of the roller for removing the surplus ink from the web,

said scraper independently supported with reference to the roller andseparated a con siderable distance from the roller to provide asui'licient interval of time for the solvent to soften the ink beforeits removal.

3. An embossing printing press provided with die and pressing devices,ink applying devices, a wiping web and a pad for pressing the wiping webupon the inked die for wiping it, combined with a scraper for scrapingthe surplus ink from the inked web and means at the delivery side of thepad for applying a solvent to the inked web before it reaches thescraper, said means consisting of a roller over which the web passes, avessel below the roller having a wick chamber and a solvent chamber incommunicationwith each other at their lower parts, a wick in the wickchamber pressing upon the underside of the roller, and means to feedsolvent to the solvent chamber, said means for applying solvent to theinked web and the scraping means being separated at a considerabledistance apart to provide a suficient interval. of time for the solventto soften the ink before its removal.

l. In means for removing ink from a wiping web of an embossing printingpress, a scraper over which the inked wiping web is drawn, combined withseparate guides upon opposite sides of the scraper for the web forbending the paper web over the edge ot the scraper to insure removal ofthe surplus ink without abrasion of the paper surfaces, t i forwardguide consisting of a single roller and an adjustable friction applyingmeans acting to apply friction directly to the roller to prevent freerotation of the roller and adjust the extent of drag upon the web.

5. Means in an embossing printingpress for removing ink from the wipingweb thereof, consisting of a roller over which the inked web is drawn, areservoir for solvent, a wick extending upward from the solventreservoir and in contact with the roller for applying solvent thereto ina restricted but uniform manner, said wick and reservoir adjustablevertically relatively to the roller, and a scraper arranged at thedelivery side of the roller for removing the surplus ink from the web,said scraper independently supported with reference to the roller andseparated a considerable distance from the roller to provide asufficient interval of time for the solvent to soften the ink before itsremoval.

In testimony of which invention I hereunto set my hand.
